Thread: Supercharger advice needed

Yeah, I want a roots style. From what I understand, a roots will give good boost at low RPM.

I've always wanted a forced induction engine. I'm getting older and figure if I'm ever going to do it, it had better be now.

I have a good bit of clearance between the hood and top of the engine. The Blower Shop has a 192 CI blower that can be fitted with a traditional toothed belt. The traditional drive is something I think I want. It is only 8 1/2" tall. With a low profile EFI throttle body, I think it will fit. If I could find an old 4-71 setup, even used, that would probably work too.

Two of my main concerns are making it pump gas friendly and how will it hold up to long distance trips. I know the 4-71 would hold up since they were originally on industrial diesels.

Getting good gas can be an issue in some areas. I may look into water/methanol injection. I suppose I could just carry some Race Gas additive for emergency fillup situations, but would rather not need it. Water/meth and/or boost retard might get me through times when 89 octane may be all that is available. Something like an MSD boost retard would let me easily dial in more retard if needed. I might even be able to do that through the EFI.

It's all just a plan right now, but something I would really like to make happen. I want to get educated as to what works and what I need to make it work.
